中文摘要	土地利用变化直接影响着生态系统服务功能及生态安全,在县域尺度上定量分析区域土地利用类型及生态环境效应变化,可为地处干旱生态脆弱区的精河流域绿洲水、土资源合理开发利用提供科学依据。利用1990、2000和2018年3期影像,采用梯次环方法对研究区各土地利用类型生态系统服务价值进行时空分析,并基于生态环境质量指数和生态贡献率对土地利用类型转变后的生态环境效应进行辨识。结果表明:(1) 1990-2018年研究区土地利用变化明显,建设用地、耕地、水域和草地面积增加,林地和未利用地面积减少;(2)近28 a来,研究区生态系统服务价值整体变化较大,呈先降后增趋势,2018年生态系统服务价值优于1990和2_年。以城市为中心的梯次环方法分析结果显示,1990和2_年研究区南部地区生态系统服务价值整体高于北部地区,生态系统服务价值高值区出现在S5~S7梯次环;2018年北部地区生态系统服务价值高于南部地区,生态系统服务价值高值区出现在N6~N8梯次环;(3)1990、2000和2018研究区生态环境质量指数分别为0.147,0.120和0.194。研究区土地荒漠化以及林地、草地转为未利用地是在土地利用层面导致生态环境退化的主要原因,未利用地转为林地、草地以及艾比湖水面的恢复是促使研究区生态环境质量改善的主要原因。
英文摘要	Land use change can directly affect ecosystem service function and ecological security.The quantitative evaluation of the eco-environmental effects of land use change at the county level can provide a scientific basis for the rational development and utilization of water and soil resources in the oasis of Jinghe River Basin.Three phases of images in 1990 (encouraging land reclamation),2000 (implementing ecological protection) and 2018 (after implementing ecological protection)were used to calculate the land use types and introduce the method of echelon ring to analyze the ecosystem services value.Furthermore,the eco-environmental effects of land use change were identified by using the eco-environmental quality index and the ecological contribution rate.Results show that:(1) From 1990 to 2018,the land use in the study area changed significantly.The total area of construction land,cultivated land,water area and grassland increased while the total area of woodland and unused land decreased;(2) In the past 28 years,the ecosystem services value in the study area has changed greatly.The trend was to be decreased first and then increased.The overall ecosystem services value in 2018 is better than that in 1990 and 2000.Based on constructing a gradient loop which took the city as the center,the spatial characteristics of ecosystem service value were analyzed.Results indicate that the ecosystem services value of the southern parts of the study area was higher than the northern parts,and the high value appeared in S5-S7 echelon ring in 1990 and 2000.While in 2018 the ecosystem services value of the northern parts of the study area was higher than the southern parts,and the high value appeared in N6-N8 echelon ring (48-64 km);(3) The eco-environmental quality index of 1990,2000 and 2018 were 0.147,0.120 and 0.194,respectively.The main reasons for eco-environmental degradation were land desertification and the transformation of forest and grassland into unused land,and the main causes for the improvement of eco-environment quality were the transformation of land use from unused land into forest and grassland and the restoration of Ebinur Lake.
